Acccount error when clicking on the option (E_INVALID_STEAM_TICKET)

I have been able to play the game completely fine before & still can, however when I click on the 'account' option on the main menu it opens a page that says E_Invalid_Steam_Ticket. That's the only thing on the page, other than a link to the Klei website. I cant remember the last time I clicked on this option but it hasn't affected me so far. Should I be afraid of it doing something?

Hey there, the E_INVALID_STEAM_TICKET error is indicated when something happens in the background (that disrupts connection) while Steam is trying to connect your game to our servers.

Most likely there was something like the game accidentally being closed, or a temporary loss of internet connection that may have affected server connection. Try restarting your computer, ensure that you are on a wired (not wireless) internet connection, and you should be good to go.
